Licensed in the 1930's, apparently as XE2CK, but changed to
XE2IK;
He was arrested for espionage in 1941, (amateur radio in Mexico
was banned from 1st December 1941).
He was an influential business man; the top dog in espionage, not
small fry.
He enjoyed some hospitality in a penitentiary, but political
strings were pulled; he appears in the 1946 American Callbook.

"Several entrepreneurs in the
Mexican city of Monterrey actively supported the activities of
Nazi espionage against the United States during the Second World
War as a fifth column, according to the book "Operation
Pastorius" by journalist and writer Juan Alberto Cedillo.

"Entrepreneurs of German
origin and Mexican companies who collaborated with officers of
the Army of the Third Reich, who were sent to Mexico to open an
operations center for the entire American continent specialized
in espionage," Cedillo told Efe.

He said that the chief of Nazi
espionage in Monterrey, was the businessman Otto Guido Moebius, a
powerful businessman from northern Mexico who managed an
industrial emporium in that city and who maintained links and
alliances with some of the big companies in the city.

The father of Moebius had
collaborated in the founding of companies that today is known as
Vitro and Banorte, two of the most important industrial and
financial corporations in Mexico.

In the book titled
"Operation Pastorius, the history of Nazi espionage from
Monterrey" (editions of the Autonomous University of Nuevo
Leon, 2010) counts as the intelligence service of the Nazi army,
sent a team of spies to Monterrey to know the war capacity of the
United States, due to the proximity to that country.

Moebius put his companies at the
disposal of Abwehr officers to carry out industrial espionage on
the United States and also collaborated in the smuggling of
strategic raw materials, such as mercury, to send them to
Germany.

He also tried to collaborate in
the Abwehr's plan known as "Operation Pastorius," which
consisted of the sabotage of the US war industry, for which they
sent explosives specialists who arrived in the United States in
submarines and pretended that they also arrived across the border
with Mexico.

In addition, they chose Mexico as
the center of operations because, from the first months of 1938,
they received large amounts of oil refined in Hamburg for the
Lutwaffe fleet, a weapon that Adolf Hitler considered strategic
for their projects.

Moebius and the main agents of
the Abwehr were captured in the Mexican Republic thanks to
pressure from the United States, but because he operated with the
support of high Mexican officials and military officers, he was
detained for a short time.

The activity of the Nazi agents
and of numerous Mexican businessmen and politicians is explained
because they counted on the protection of important Mexican
politicians, among them the same Minister of the Interior Miguel
Aleman, who had relations with Hilde Krüger, an agent of the
German minister of propaganda, Joseph Goebbels."
